Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention provides a gravel compaction device and a lifting and positioning device that precedes this device in the working direction, which are disposed between carts, and a gravel storage device that is connected to a gravel bed. Cleaning and subsequent gravel beds of railway tracks by means of a cleaning machine with a variable outlet for storing gravel during cleaning and an associated gravel compaction machine arranged at the forward end in the working direction on the frame of the cleaning machine. Concerning a combination of self-propelled machines for compaction.

[Prior Art and Problems Therewith] Applicant's Canadian Patent No. 1,191,739 discloses a cleaning machine and associated leveling, compacting, and The invention relates to a combination of self-propelled machines for the cleaning and subsequent compaction of gravel beds of railway tracks with lifting and alignment machines.

The compaction machine comprises a compaction device further comprising a compressible compaction tool configured to penetrate the gravel and be vibrated by the drive. With such a compaction device, a comparatively strong sleeper support surface can be ensured by compressing the vibrating compaction tools together in the gravel below the sleepers. Disadvantageously, securing the sleeper support surface on the gravel below the sleepers immediately after the gravel cleaning machine in this way does not allow the cleaning gravel that collects from the cleaning machine to be routed accurately to the conveyor belt via the track panel. This is difficult unless it is possible to release it into the sleeper frame, which often results in more gravel being collected elsewhere but not enough where the compactor penetrates the gravel. In order to be able to in fact ensure a permanent and very thoroughly cleaned gravel bed, it is often necessary to ensure a good distribution of gravel across the entire cross-section of the track in this way. Therefore, it is necessary to use a gravel leveling and sweeping machine after the cleaning machine.

In addition, the applicant's U.S. Pat. No. 4,430,944 discloses that the track can be lifted to a considerable height and that the waste build-up from the cleaning machine in front of it (in the working direction) is removed by the track compaction machine. a railway track consisting of a gravel cleaning machine coupled with an endless conveyor belt arranged above the frame of the machine and a track compaction machine carried above it towards the waste accumulation loading vehicle by another small endless conveyor belt This paper describes a combination of self-propelled machines and a method for cleaning gravel floors. Between two carts of a compaction machine that are arranged far apart from each other, the compaction machine and the track lifting device in front of it can be displaced in the longitudinal direction with respect to the frame of the machine by the power of the power section, It makes it possible to compact the gravel under the individual sleepers in advance and continuously (without stopping). In front of the second truck of the compaction machine there is a further track lifting device, which makes it possible to ensure a particularly high sleeper support surface, so that the cleaning and leveling chain of the cleaning machine can pass along with it. Sufficient gravel can be taken in from the gravel bed to A similar known gravel cleaning machine (U.S. Pat. No. 4,538,687) also pushes waste accumulations forward in the working direction on a track compaction machine and is provided with a supporting carriage and gradually moves from sleeper to sleeper. The compacting, lifting and leveling device of said machine is arranged on its own tool frame, which is connected to the frame of the machine by a longitudinal displacement drive for advancement.

Continuous (non-stop) track leveling and compaction of the type in question;
Lifting and positioning machine (German patent No. 2 and 1 of the applicant)
35,369B) has already been used very successfully in practice. This compaction machine consists of a main machine supported by a trolley and a tool frame pivotally connected to the main machine, the compressible and vibrating tool being configured to be inserted into the gravel. This frame supports two compaction devices located far apart from each other.
It is supported on a track between two bogies. On this tool support frame, which includes a supporting and guiding carriage and is pivotally mounted on the frame of the main machine at a distance from this carriage in the longitudinal direction, a compaction device is located immediately in front of the supporting and guiding carriage. , itself following the orbital lifting and alignment device with associated lifting and alignment drives. When mounted on a continuously advancing (non-stop) main frame, the tool support frame configured to advance gradually in sleeper units is driven by the main frame under the power of a longitudinal piston/cylinder type hydraulic power section. It is arranged to be displaced in the longitudinal direction of the machine relative to the frame. This type of track compaction machine offers a level of comfort hitherto unobtainable with respect to on-board working conditions and also achieves high performance levels and considerable energy savings, inter alia in the main frame axle drive and The load on the brakes was reduced, since the main frame no longer started and stopped abruptly, or vibrations were no longer transmitted, especially to the driver's seat.

Finally, the applicant's U.S. Pat. No. 4,257,331 describes a combination of self-propelled machines of the type initially mentioned for cleaning and then compacting the gravel beds of tracks. . This self-propelled machine combination consists of a gravel cleaning machine and an associated gravel compaction machine, the gravel compaction device and the lifting and positioning device preceding it in the working direction being two parts of the gravel compaction machine. The present invention includes a gravel storage device with a variable outlet for gravel that accumulates during cleaning operations, located between the two carriages and located on the machine frame of the gravel compaction machine at its front end in the working direction. In this case, the cleaned gravel that accumulates from the cleaning machine is transferred to an endless conveyor that extends from the rear end of the cleaning machine to the connected gravel compaction machine.
A belt transports it to the vicinity of the gravel storage device. From this gravel storage device, the gravel can be distributed onto the gravel bed through a discharge chute which can be actuated by a drive.

Such a machine configuration is intended to allow the vehicle to immediately run at relatively high speeds on the track in order to ensure improved compaction of the gravel bed. The gravel compaction tool of this gravel compaction machine consists of a so-called high-thrust deep compaction tool that only receives vertical acting force without compressive action, so it ensures a much improved compaction state in the sleeper frame. However, the gravel below the sleepers often still has to be compacted by compacting and vibrating compaction tools that penetrate into the gravel. The following is stated on page 3, lines 43 to 46 of this document. ``Furthermore, the corrective work that must be carried out later, using a compaction machine with compressible compaction tools to form the sleeper support surface, and the degree of settlement of the track under the weight of the following train will be It is also an object of the present invention, which has its origins in U.S. Pat. No. 4,257,331, to maintain a relatively small To provide a self-propelled machine combination capable of ensuring a more accurate and durable positioning of the track with compacted sleepers after the machine has been used only once, after cleaning the gravel bed. There is a particular thing.

According to the invention, this object is achieved by the combination of the self-propelled machine mentioned in the introduction, in which the gravel compaction machine comprises a compaction machine configured to oscillate by means of a drive unit that penetrates the gravel. at least one with a possible compactor
A gravel compaction machine is configured as a track compaction, leveling, lifting and positioning machine consisting of two sleeper compaction devices, and also supplies cleaned gravel to a gravel storage device on the machine frame of the track compaction machine. Alternatively, a conveyor device for taking in is provided. Such self-propelled combinations with built-in cleaning machines, rather than individual gravel leveling or distribution machines, are effective by penetrating compaction tools down to the gravel below the bottom edge of the sleepers. A suitable sleeper support surface to be compacted is only ensured in such vehicle combinations. Immediately after using such a self-driving combination, the track, firmly compacted in the corrected position, can therefore withstand trains traveling at relatively high speeds. The independence from a continuously advancing cleaning machine, achieved by the arrangement of the conveyor for feeding and picking up the cleaned gravel on the frame of the track compaction machine, can also be achieved, e.g. This is particularly advantageous since it can also be used. However, due to the possibility of such independent use, vertical deviations of the gravel bed due to repeated thrusting of the compactor into the gravel can be avoided, for example if the track produces large deviations in its vertical position. It is also possible to compact gravel that has not yet been compacted in exactly the same way as when the correction is relatively small and therefore easier to correct. in this way,
Ensures a uniformly compacted support surface for each sleeper, regardless of the forward speed of the cleaning machine and regardless of the highly significant deviations in track level that result from complete renewal of the gravel bed. can do. The supply of cleaned gravel to the gravel storage device, if necessary, preferably occurs when the distance between the compaction machine and the cleaning machine is reduced to a minimum.

One particular preferred embodiment of the present invention is for supplying fresh or cleaned gravel to a gravel storage device and/or for further transporting excess gravel that accumulates during cleaning, and for supplying fresh or cleaned gravel to a cleaning machine. It is characterized in that the conveyor device is configured to reciprocate in the working direction of the machine combination or in the opposite direction for the supply of gravel. This versatility in the transport of cleaned gravel is such that the same conveyor device carries away excess gravel from the cleaning machine and preferably compacts it if not enough cleaned gravel is available. If it can be used both for transport over the length of the machine to the cleaning machine, it offers a particularly effective and wide range of suitability to the prevailing gravel conditions. Furthermore, the same configuration ensures that the required amount of cleaned gravel is always obtained within the above-mentioned range of the self-propelled combination compaction device when carrying out uniform graveling and compaction of the tracks.

In one embodiment of the invention, the conveyor device comprises:
Means for conveying the gravel, e.g. element and preferably to at least one drive which lifts the front end and preferably also the rear end of the endless conveyor belt during actual work operation. Such a conveyor device, which includes guiding elements for selectively conveying the cleaned gravel to the compaction machine and to the gravel storage device, can be used regardless of the varying accumulation of cleaned gravel. , which is particularly effective in laying gravel on the track evenly. This uniform gravelling operation, combined with compaction of the track in a single motion by a compaction machine, makes it possible to ensure a particularly uniform sleeper support surface and a particularly stable lateral position of the track.

According to this embodiment, excess gravel can be transported very easily over the entire length of the track compaction machine. This is particularly advantageous, for example in the vicinity of stations where lateral treatment is not possible.

In another advantageous embodiment, the invention provides that the conveyor device is arranged in a machine frame above the track compaction machine;
and a single endless conveyor belt, preferably configured to reciprocate in both directions, with devices located above the gravel storage device for conveying the gravel or for conveying it to further distances as required. It is characterized by being formed by an adjustable deflection plate. The arrangement of only one conveyor belt above the track compaction machine provides a particularly simple and unhindered conveyance of the cleaned surplus gravel over the entire machine, for example for loading onto a subsequent loading vehicle. Adjustable deflection plates are provided within the area of the gravel storage device, so that the required fractional quantities of gravel can be easily and continuously delivered to the gravel storage device as required, without interrupting the continuous gravel transport. The storage device can be filled.

In another advantageous embodiment of the invention, the conveyor device is arranged in front of the compaction machine and is provided with brushes and an ascending conveyor belt, preferably configured to move vertically and extending up to the gravel storage device. It comprises a vertically movable gravel intake device and preferably has an endless conveyor belt extending from the rear of the compaction machine to the gravel storage device. Such a gravel uptake device in the form of a conveyor belt combined with a track compaction machine is even more independent from the preceding cleaning machine, since excess gravel can be taken up directly from the track independently of the sweeper area. allows the use of compaction machines. Rising conveyor
The gravel lifted by the belt can be discharged into a gravel storage device if required or, in the case of vertical movement, placed at the rear end of the machine for further conveyance to the following loading vehicle. It can also be discharged onto a conveyor belt.

Conveyor devices for supplying and transporting the cleaned gravel further are arranged one after the other on the machine frame of the track compaction machine and extend from the rear of this machine to the gravel storage device and further on the compaction machine. Consisting of two endless conveyor belts extending to the front so as to be loaded by another preferably pivoting endless conveyor belt located at the rear end of the cleaning machine in its longitudinal direction above the machine frame. configured, one or both endless conveyors
Another advantage is obtained by the fact that the belt is connected to a device for selective conveyance of cleaned gravel in the vicinity of the gravel storage device. Such a construction of the conveyor device and the device for selective conveyance of cleaned gravel, in which one of the conveyor belts is located in the longitudinal direction of the machine after the other, is structurally simple and, if necessary, can be installed in large numbers It is relatively easy to transport gravel through different routes. For example, excess gravel can be conveyed directly from the cleaning machine via a conveyor system to the loading vehicle or, if the amount of gravel is too low, from the loading vehicle in the opposite direction to the cleaning machine. At the same time, the selective conveying device is always capable of conveying some or all of the gravel to the gravel storage device as required.

In another advantageous embodiment of the invention, the endless conveyor belt extending to the gravel storage device overhangs the front end of the compaction machine and has a drive arranged at its front end on the machine frame of the compaction machine. The cleaning machine is configured to be moved longitudinally to the cleaning machine by the power of the section. The longitudinally movable structure of the front conveyor belt of this conveyor device advantageously allows for varying degrees of overhang beyond the front end of the machine. This ensures an unobstructed and uninterrupted flow of gravel from the cleaning machine to the following compaction machine, even if relatively small changes occur in the distance between these two machines, which are configured to move independently of each other. Carry out transportation without any damage.

In another preferred embodiment of the invention, a compaction machine for continuous, unstoppable advancement with the cleaning machine comprises:
It has its own tool frame that supports compaction, lifting and alignment equipment and is provided with a support carriage connected to the drive for longitudinal displacement with respect to the machine frame.

Such a configuration of the working devices on the tool frame, which can be moved in the longitudinal direction, reduces the load on the machine frame and significantly improves the performance regarding compaction operations, making it possible to continuously receive gravel from the cleaning machine. Make it. Moreover, this gravel take-up device, which is located at the front end of the compaction machine, can be used even more effectively to continuously pick up excess gravel from the gravel tracks as the work progresses.

According to the invention, this self-propelled machine combination also provides that the gravel storage device preceding the compaction machine is associated with a variable outlet and is arranged adjacent to each other in the longitudinal direction of the sleepers, so that the compaction section and the corresponding sleeper It may also be constructed to consist of four discharge chutes intended to be arranged on the frame and two further discharge chutes cooperating with the variable outlet and preferably located behind the discharge chutes in a given working direction. can. The configuration of four such ejection chutes in the longitudinal direction of the sleepers is as follows:
Provides a controlled supply of gravel to the sleeper support surface. At the same time, if too little gravel is discharged by one of the two adjacent discharge conveyor belts of the cleaning machine, then the remaining discharge chute is delivered even more via the associated half discharge chute! It is even possible to release 7 quantities of gravel.

Finally, another advantageous embodiment of the invention provides that the vertically displaceable device located longitudinally of the machine in the working direction behind the compaction, lifting and positioning device comprises a tool frame of the compaction machine. characterized in that the device is also preferably arranged for displacement in the longitudinal direction relative to the compaction machine. Such a combination of a compaction device with a rear sleeper compaction device has the advantage that the gravel in the sleeper frame is compacted immediately after the compacted sleeper support surface has been secured by the compaction device. has. For this reason, immediately after the use of these two machines, the sleeper support surfaces secured by compaction are "protected", resulting in even greater durability of the track.

Two examples of embodiments of the invention are described in detail below with reference to the drawings.

As can also be seen from the plan view in FIG. 3, the gravel storage device 36 is arranged on the machine frame 21 between the front carriage 20 and the tool frame 30. As shown in FIG. 3, this gravel storage device 36 preceding the compaction device 25 comprises four discharge chutes 38 associated with variable outlets 37 and arranged adjacent to each other in the longitudinal direction of the sleepers. . These unloading chutes 38 are connected to the sleeper frames 3 corresponding to the compaction section.
It is intended to be placed on 3. Export chute 38
At the rear in the working direction are located two further discharge chutes 39 cooperating with the variable outlet and arranged between the rails 7 . This outlet 37 can be varied by a hydraulically operated flap 40 pivoting around a spindle extending transversely to the longitudinal axis of the machine. For clarity,
This flap 40 is not shown in FIG.

A conveyor device 41 , 42 is provided on the machine frame 21 of the orbital compaction machine 3 for transporting the cleaned gravel into and out of the gravel storage device 36 . Gravel storage device 36
The conveyor device 41, which is configured for supplying gravel to the conveyor and/or for further conveying surplus gravel to the following gravel conveying and loading vehicle 5, is a device for conveying the gravel during the work run, i.e. a guiding element. 43 and a drive cylinder 44. A comparing device 41 mounted on the upper side of the machine frame 21 comprises two pivoting conveyor belts 45, one behind the other and extending from the rear of the machine to the gravel storage device 36, and a drive at the front end of the machine. 46 and a conveyor belt 47 displaceable in the longitudinal direction. The other conveyor device 42 is configured as a gravel intake device 48 and consists of a vertically displaceable lifting conveyor belt 50 located at the front end of the machine and extending from the brush 49 to the gravel storage device 36. A gravel removing brush 51 rotatable in the longitudinal direction of the railroad ties is located behind the gravel storage device 36.

The track leveling, compaction, lifting and positioning machine 52 shown in FIG. It is composed of The rear end of the track compaction machine 52 on the machine frame 53 is capable of being compacted in pairs with respect to each other and is provided with pierces into the gravel bed for simultaneously compacting the gravel under two adjacent sleepers 57. After this, a vertically displaceable two-sleeper compacting device 58 is arranged which includes a compacting tool 59 which can be vibrated by means of a drive. At the front of this compaction device 58, a rear end portion is connected to the machine frame 53 by a lifting and positioning drive unit, and a front end portion thereof is connected to the machine frame 53 so as to be freely pivotable. There is a lifting and positioning device 60.

At the rear of the lifting and positioning device 60 are disposed a pair of mutually closeable gripping rollers for gripping the rails and a pair of positioning rollers configured to be used with the track. There is. The leveling/alignment reference device 61 is provided for leveling/aligning the track. A gravel storage device 62 connected to the machine frame 53 at the front end of the machine includes four discharge chutes 64 associated with the variable outlet 63 below and arranged adjacent to each other in the longitudinal direction of the sleeper. These discharge chutes are arranged on sleeper frames 65 corresponding to the compaction section.

A conveyor system 57 consisting of a single endless conveyor belt 66 is provided for transporting cleaned gravel into and out of the gravel storage device 62 . This conveyor extending from one end of the machine to the other end above the machine frame 53
The belt 66 includes a device in the form of a deflection plate 68 for feeding or further conveying the gravel as required.

Under the control of a drive 69 fixed to the gravel storage device 62 in conjunction with a central control device, the deflection plate 68 can be moved across or laterally to the conveyor belt 66 by remote control. It can be rotated about a vertical axis towards a parallel position. Gravel conveyor belt 7 extending beyond the gravel compaction machine in front
0 is shown above the front end of conveyor belt 66. Another vertically displaceable conveyor device 72 in the form of a gravel take-up device 71 with brushes and a rising conveyor belt 73 is provided at the front end of the machine for taking in excess gravel from the track.

The working modes of the machine organization 1 shown in FIGS. 1, 2 and 3 will be described in detail below.

The cleaning machine 2 and the track compaction machine 3 used in conjunction with each other move continuously along the track 9 at a distance apart, which distance is proportional to the trajectory relative to the forward speed of the cleaning machine 2. is maintained approximately constant by associating the speed of movement of the compaction, lifting and alignment machine 3. The gravel lifted by the cleaning and conveying chain 13 and separated from the waste accumulation in the sieving device 14 passes partly via deflection plates which can be adjusted as required onto the discharge conveyor belt 15. , via these conveyor belts back to the gravel bed, and a portion (in the direction of the solid small arrow in FIG. 1) passes onto a conveyor belt 17 which extends beyond the rear end of the machine.

The gravel carried away on this conveyor belt 17 no longer needs to be returned onto the gravel bed, but this is the case if the waste accumulation is minimal and with regard to the loosening of the previously compacted gravel, present after cleaning. This is because the amount of gravel used is often too large. From the overhanging conveyor belt 17 of the cleaning machine 2, excess gravel is conveyed in the direction of the small solid arrow to the front conveyor belt 47 of a conveyor device 41 connected to the orbital compaction machine 3. This longitudinally displaceable conveyor belt 47 is displaced in the longitudinal direction of the machine such that its rear overhanging end is located directly above the guide element 43. In the illustrated position of the guide element 43, the gravel is transferred from the conveyor belt 47 to the conveyor device 4.
1 to the rear conveyor belt 45, but not to the lower gravel storage device 36. A corresponding longitudinal displacement of the adjusting cylinder 44 causes the pivoting conveyor belt 45 to pivot about a horizontal axis such that its front end is below the conveyor belt 47. From this pivoting conveyor belt 45, the surplus gravel ends up on the conveyor line of the gravel storage and loading vehicle 5, where it is loaded with gravel. At the same time, the excess gravel present on the track 9 is conveyed by the brushes 49 of the gravel uptake device 4B to the ascending conveyor belt 50, from which it is discharged to the gravel storage device 36. From the gravel storage device 36, the accumulated gravel is sent to the sleeper frame 33 via a variable outlet 37 as required.

Another possibility for selective conveyance, which in this example is applicable if there is too little gravel in the gravel storage device 36, is to rotate the guide element 43 to the left, ie to the rear, so that the gravel discharged from the conveyor belt 47 A portion of the gravel is discharged to the gravel storage device 36 or remains on the pivoting conveyor belt 45.
This is the case when it is to be emitted to This means that a portion of the excess gravel can be used to fill the sleeper frames 33 as required, and the remainder is loaded onto the gravel storage and loading vehicle 5. If the amount of gravel in the gravel storage device 36 is too small, the guide element 43 can of course be rotated completely to the left, i.e. to the rear, so that the entire amount of gravel conveyed by the conveyor belt 47 is transferred to the gravel storage device. It will be used for filling 36. Such selective adjustment of the gravel flow rate according to requirements is carried out without disturbing the progress of the work.

Another possibility for the selective transport of gravel is that after a previous displacement of the conveyor belt 47 in the working direction, the dotted line (FIG. 2)
2. Raise or extend the ascending conveyor belt 50 to the position shown at . Thus, the discharge conveyor belt is already cleaned by the cleaning machine. In this way, the discharge conveyor has already been cleaned by the cleaning machine.
Excess gravel discharged onto the track via the belt 15 and taken in from the track 9 by the gravel intake device 48 is
It is discharged directly onto the pivoting conveyor belt 45 and from there to the gravel storage and loading vehicle 5.

However, the structure according to the invention also makes it possible to convey the cleaned gravel from the gravel storage and loading vehicle 5 to the gravel storage device 36 and/or directly to the discharge conveyor belt 15 of the cleaning machine 2. Make it. Such a return of gravel in the working direction can be carried out, for example, when the accumulation of waste accumulation increases suddenly and significantly and insufficiently cleaned gravel cannot be obtained, or when old gravel is completely removed along certain sections of the track. It is needed when it becomes so dirty that it must be removed. For such a turn in the direction indicated by the small dotted arrow in FIG.
must first be rotated about a horizontal axis extending transversely to the longitudinal axis of the machine (dotted line position in FIG. 2) by actuation of the front and rear adjustment cylinders 44. Then,
The front end of the discharge conveyor belt of the gravel storage and loading vehicle 5 must be moved onto the pivoting conveyor belt 45. The overhang conveyor belt 17 of the cleaning machine 2 is connected to the joint 1
6 below the front end of the conveyor belt 47 of the compaction machine 3 (dotted line position in FIG. 1).
be moved to. Conveyor device 4I and cleaning machine 2
The cleaned gravel is transported from the loading vehicle 5 over the track compaction machine 3 onto the discharge conveyor belt 15 of the cleaning machine 2 when the conveyor belt of the cleaning machine 2 is set to move in a direction corresponding to the working direction. . The gravel conveyed from this conveyor belt 15 is discharged into the last exposed earth mound.

In this case, a portion of the gravel (or the entire amount of gravel) can be conveyed to the gravel storage device 36 by correspondingly positioning the guide element 43. If a particularly hardened section of the track is transported and the gravel accumulation becomes too high again, the direction of transport is immediately reversed for the transport of gravel from the cleaning machine 2 to the loading vehicle 5. During the entire course of continuous forward operation of the machine arrangement 1 according to the invention, the track 9 is compacted by a compaction device 25 which moves forward in steps, sleeper by sleeper, together with the tool frame 30, and the gravel in the sleeper frames 33 is compacted by the device. Compacted by 32. At the same time, gravel is discharged as required from the variable outlet 37 of the gravel storage device 36 in front of the compaction device (in the working direction) to the track 9, so that a uniform gravel load is achieved for the subsequent compaction operation. Orbital panels will always be present. Gravel stripping brush 51 rotates around an axis extending across the longitudinal axis of measurement
The gravel existing on the sleeper 8 is peeled off against the sleeper frame 33 at the rear.

The working mode of the track compaction machine following the cleaning machine shown in FIG. 4 is as follows. That is, this working mode is
Only the overhanging conveyor belt 70 is shown stepping in the direction of the double arrow 74 behind the continuously advancing cleaning machine. Gravel conveyor belt 70 must have an appropriate overlap with conveyor system 67 of orbital compaction machine 52 to span the small changes in distance that occur between the two machines. Excess gravel accumulating from the preceding cleaning machine is discharged from the gravel conveyor belt 70 onto a conveyor arrangement 67 and conveyed by the conveyor arrangement 67 against the working direction. If the deflector plate 68 is placed laterally adjacent the conveyor belt 66 in the longitudinal direction, all gravel will be routed through the gravel storage device 62 to the track line.

It is sent back to the loading vehicle following the compaction machine 52. However, if too little gravel is present in the gravel storage device 62, the deflection plate 68 can be rotated partially across the conveyor belt 66 by actuating the drive 69, so that the conveyor A portion of the gravel delivered onto device 67 is delivered to gravel storage device 62 . Regardless of whether such gravel is transported above the machine frame 53,
Furthermore, excess gravel is taken in directly from the track by a gravel taking-in device 71. This gravel is transported by the ascending conveyor belt 73
directly to the gravel storage device 62. If there is too little gravel in the sleeper frame, the gravel correspondingly flows out of the gravel storage device 62 or via its variable outlet 63. The track is therefore uniformly graveled for later compaction by compaction device 58.

With this track compaction machine 52, gravel can also be conveyed from a subsequent gravel conveying and loading vehicle towards a preceding cleaning machine if necessary. For this purpose, the front end of the conveyor belt of the loading vehicle is connected to the conveyor belt 66 of the compaction machine (as already mentioned with respect to FIG. 1).
and the gravel conveyor belt 7 of the cleaning machine moved below the front end of the conveyor belt 66 of the compaction machine 52
It only needs to be sent over approximately the entire 0.
